Balanced Performance: Machined for high-speed operation to minimize mechanical vibration

improving overall fuel efficiency and safety

Always reference the compressor model number on the rating plate

allowing the contactor to re-engage the compressor without manual intervention

making it suitable for modern heat pump systems with expansion in both directions
